' GATE- Application filed September 1 925. Serial No. 53,861.

This invention. relates to animproved gate and seeks, among other objects, to provide a novel gatestructure wherein the gate may be opened by a vehicle approaching the gate, and,after the vehicle has passed through, again closed by the vehicle.

The invention seeks, 'as a Q to provide a novel mounting for the. gate whereby the gate may be caused to swing to open or closed positioni And the invention seeks,'as a still further objectfto provide an improved 'and simple operating mechanism forthe gate. Other objects of the invention not above specifically mentionedwill appear'asthe description proceeds. In the accompanying drawings: Figure 1 is a plan view of'my improved gate.

Figure. 2

is a transverse vertical 7 sectional I fvie'w on theline 2 -2 of Figure '1, looking in thefdirection indicated by the arrows.

, v Figure 3 is a detail perspective view showin the crankshaft which swingingly supports the gate. Figure 4 is a ticularly showing the latch.

Referring now more particularly to the V drawings, wherein I have illustrated the preferred embodiment of the invention, the numerals l0 and 11 indicate suitable gate posts at opposite'sides of a roadway. Fixed to the post 10 are vertically alined brackets 12, which may be formed of eye bolts or screw eyes and journaled through the eyes of said brackets is a crank shaft 13. Extending from the shaft near its upper end is a long crank 14, and extending'from the shaft near its lower end is a short crank 15, the shaft and said cranks being an integral structure. in parallel relation to extend laterally from the shaft and at their outer ends, are provided with upstanding trunnions 17. As will be observed, the cranks rest on the brackets 12 for supporting the shaft 13 against downward movement.

The gate is lndicated at 18. This gate preferably comprises a rigid metal frame 19, and fixedeto one end of the frame near the upper edge of'the gate is a short hinge bracket 20 apertured to fit over thejtrunnion 17 of the long crank 14, While near the lower edge of the gate is provided a long hinge bracket 21 apertured to fit over.

the trunnion 17 of the short crank 15. The

further obj ect detail perspective View par The cranks are disposed gate is thus mounted to swing 'Supon'sa'idcranks and, as brought out in Figure-2,

the inner end of the gate lies in parallel relation to the shaft 13. Fixed to the post 11 is a keeper 22, and fixed to the frame of the gate at the outer end thereof. is

a channel-shaped latch supporting plate .23 i in which is pivoted a latch 24 engageable with the keeper for securing the gate closed.

As shown in detail in Figured, the lower aside-flange ofthe plate'23may be'bent'up at its forward end toprovide a lug 25-for supporting the free end portion of the latch against. undesired downward movement and maintaining the latch in a substantially hori-. zontal positionto cooperate with the keeper. Countersunk in the roadway to lie flush. therewith at one side of'the-gatei's a trans 'versely disposed sill-26, and similarly'arranged at the opposite side of the gate is a 7 like sill 27. These sills are] preferably'of cement, although other suitable material may be employed. Mounted upon the sill 26'is a crank-rod 28 having cranks 29' and 30 disposed at substantially a rightangle to each-other, and mounted upon -the'sill'27 is a crank rod 31 having similarly disposed cranks 32 and I J ournaling the rods are pairs of bearings 34 which are disposed close at opposite sides of the cranks of thelrods and are bolted or otherwise secured to the sills 26 and 27. Fixed to corresponding ends 7 of the rods 28 and 31 are crank arms 35, and fixed to the lower endof the crank shaft 13 detail in Figure 3, the shaft is provided near its lower end with a squared portion 37 to receive the arm 36,- and screwed on the lower end of said shaft is a nut 38 detachably securing the arm in position. Connecting the arms 35 of the crank rods with the turned ends 40 engaging through said crank arms and secured bysuitable pins.

of the gate is a crank arm 36. As shown in crank arm 36 are rods 39 having laterally As shownin Figure 1, the cranks 29, 30, 32 and 33 of the rods 28 and 31 are so arranged that when the gate is closed, the

cranks 29 and 33 upstand from the road-' way while the cranks 30 and 32 lie parallel to theroadway close thereto. Accordingly, a vehicle moving along .a roadway and approaching the gate from one direction, may be caused to travel'over the crank 29 of the rod 28 with the result that this crank will the 1 foregoing description, such-imovement 1 of the. crank 29i will cause the cr-ank shaft crank rod 28 is,,as shown in Figure 1,

end-of thegate' so that the latch 24 Will be 3 'r'ovided at, oneside of the roadway for h m 'ting the gate'inits opening movement. As the vehiclecont'inues P along. the roadway, said vehicle may then be caused; to ztravel fever the crank v'32 =0f the-rod '31, Whenthe r *crank'shaftl3j'gvvillgbe rotated tothe right, thus-causingthe;,gate rtoclose. As the, gate approaches closedpositiomthe-latch 24 will, of: ghoul-Se; ride over the "keeper. 22 into enfgagement therewith fornagain securing the agate closed. As Willbe; perceived; when the crank 29 is swungidown, incident to the ap- -proach,o'fithe vehicle,tthe crank 32 will-be 30 swung up toactive position so that; the 2-Wl1G6lS of the vehicle may subsequently be f 'clo sing thegatei gimilarlyyavehiclemov- 1 y; i-n'g a-longthe roadway and approaching the I l 1370f the gate to be'rotated' to the left and,
